Import Dimethyl Sulfoxide — Buy in Bulk from Supplier in China

Dimethyl sulfoxide (DMSO) from Hebei Tianao Technology Co., Ltd is a high-purity organosulfur compound with the chemical formula (CH3)2SO, supplied as a clear, colourless liquid with a faint garlic-like odour. The product is classified as industrial grade with a minimum purity of 99.5%, a boiling point of 189°C, and a melting point of 18.5°C. Water content is held below 0.1%, and the acid number is less than 0.01 mg KOH/g, consistent with standard industrial specifications for solvent-grade DMSO.

This material is typically produced via the oxidation of dimethyl sulfide, a byproduct of the wood pulp industry, and purified through distillation and molecular sieving. It exhibits low viscosity and high thermal stability, enabling it to dissolve polar and non-polar compounds including peptides, polymers, and salts. The compound’s membrane-permeating ability is well documented in pharmaceutical literature, but this listing does not claim medical or pharmaceutical-grade certification. It is intended for industrial synthesis, chemical processing, and laboratory use only.

Buyers in pharmaceutical manufacturing, organic synthesis labs, and polymer processing use this DMSO as a reaction solvent, cryoprotectant, or cleaning agent. Packaging is available in 200L steel drums or 1000L IBC totes, with bulk quantities offered under FOB Tianjin or CIF terms. Minimum order quantities are confirmed directly with the supplier. Lead times typically range from 10 to 15 days after order confirmation, depending on production scheduling and port availability.

Hebei Tianao Technology Co., Ltd is a chemical manufacturer based in Hebei Province, China, with a verified export license and a history of supplying industrial solvents to international buyers. The company operates a production facility focused on organic sulfur compounds and maintains a harbor-level trust tier, indicating documented customs and logistics compliance. Its response rate and average reply time are not publicly tracked, suggesting limited customer service automation.

The listing does not confirm certifications such as ISO, SGS, or GMP, nor does it state annual production volume, workforce size, or client names. The company is not listed as a distributor or trader but as a producer, based on its location and product focus. Buyers should request a certificate of analysis and batch traceability documents before placing an order. No claims about R&D capability or in-house testing labs are made in the source data.
